runtime: Convert to the new internal types package

We can now remove all the sandbox shared types and convert the rest of
the code to using the new internal types package.

This commit includes virtcontainers, cli and containerd-shim changes in
one atomic change in order to not break bisect'ibility.

Fixes: #1095
